We are always hearing about how the advancement in medical science has benefited the patients but there is a whole other side to it. The Doctors too have derived great benefit from the rapid advancement in medical science. This is due to these advanced measures many new branches of Doctorate have sprung up which were previously non existent. Moreover new machines like the ECG machines help to equip the Doctor with the knowledge of the exact condition of the patient. Based on this the Doctor will be able to give the best possible advice and take the most effective measures.
In the older days the doctors had to conduct a number of experiments in order to determine the exact condition of the patient. This would often cause the patient more pain than the actual reason of pain relief for which he came to the Doctors. Moreover the Doctors had to perform the actions based on partial knowledge and partial conjecture which carried chances of going the wrong way and could in the end become detrimental for the patient.
Doctors also have much easier to handle and reliable devices for routine work such as digital thermometers and the like. Devices of helps them to save time as the generally work faster and are much more accurate. This helps to facilitate the doctors and fastens up the speed and accuracy of procedures that would otherwise take a long time to conduct. In the end we can see that the doctors too have greatly benefited from the advancements in medical technology.

The incidence of depression increases with age. This may be because older people living on their own may be socially isolated and often worry over becoming a burden to their families. In addition, they have often lost many friends and loved ones to death, and may require multiple medications for different medical conditions (many medications can affect mood). Add to this increasing physical frailty and slowing mental faculties, and the scene is set for a depressive episode.
There is no single cause of depression. Many cases appear to be linked to abnormalities in brain chemistry. For example, it has been determined that persons at high risk of suicide have lower than normal levels of serotonin, a neurotransmitter in the brain that controls inhibitions and is closely related to mood. People with reduced levels of serotonin are therefore more likely to act on feelings such as a desire to take their own life. Conversely, increasing the level of serotonin in the brain improves mood in many cases.
Some cases of depression can be traced to inadequate nutrition. Deficiencies of certain vitamins, for example, can result in symptoms of mental and emotional disorders. Food allergies can also result in a depressed state. Hypoglycemia (low blood sugar) can cause mood swings, irrational behavior, and may set the scene for episodes of depression. One type of depression, known as seasonal affective disorder (SAD), appears to be related to insufficient exposure to sunlight.
When days are short and skies are gray and overcast, exposure to sunlight is reduced or nonexistent. This causes the retina of the eye to fail to send proper messages to the hypothalamus, which is responsible for transmitting signals that maintain the body in its properly regulated state. The end result may be a form of depression. SAD most often affects those living in northern climes during the cold months of the year.

Any person who is involved in body building, sports and competitions will know that how much he had to perform and maintain himself to achieve the best position. But sometimes a player feels that he cant reach the heights without synthetically enhancing his power and capability and intense training. One approach to boost this process is the use of anabolic steroids.
Testosterone is the main constituent in steroids is which is also known as the chief male hormone. Body is affected testosterone in two ways: -
1.) Anabolic influence: - such kind of actions helps in building the body tissue by increasing lean muscle and growing bone density.
2.) Androgenic influence: - these actions affect the sex characteristics of a man.
Some interesting information and facts had been revealed about testosterone and anabolic steroids in recent years: -
1.) Muscle size is affected by the usage of these steroids as muscle fiber hypertrophy increases in its cross-sectional area.
2.) About 300 milligrams dosage of testosterone is required to increase the bodys level.
3.) Muscles are directly affected by them.
4.) Helps in stimulation for releasing the growth hormone.
5.) They as anti-catabolic effect.
From the above facts we find that anabolic steroids like testosterone is an efficient support in muscle building and it must be taken in adequate quantity to have its effect. But the combination of anabolic steroids and chemical drugs that are generally taken by body builders can be really harmful for the body and tragic conditions can be generated.
